1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, configuration information related to hybrid automatic repeat and request (HARQ)-acknowledgement (ACK) reporting for a multicast physical downlink shared channel (PDSCH), wherein the UE is provided a plurality of group-radio network temporary identifiers (G-RNTIs) related to the multicast PDSCH for a serving cell, and wherein based on the configuration information, one of ACK/negative ACK (NACK) based HARQ-ACK reporting or NACK-only based HARQ-ACK reporting is individually configured for each of the plurality of G-RNTIs;
receiving, from the base station, downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a G-RNTI among the plurality of G-RNTIs;
receiving, from the base station, the multicast PDSCH based on the DCI; and
based on the NACK-only based HARQ-ACK reporting being configured for the G-RNTI, transmitting, to the base station, HARQ-ACK information for the multicast PDSCH on a first physical uplink control channel (PUCCH) according to the NACK-only based HARQ-ACK reporting,
wherein based on a specific type HARQ-ACK codebook being configured for the multicast PDSCH, the HARQ-ACK information for the NACK-only based HARQ-ACK reporting is generated according to the specific type HARQ-ACK codebook.
